Level of object representation and psychic structure deficit in obese persons

The structural deficit and external regulation hypotheses of addiction state that addicts do not have adequate psychic structure with which to regulate painful affects internally. They instead use their drug of choice as an external regulator to self-medicate painful affects. This study tests whether the hypotheses can be applied to obese persons, for whom food may be the drug of choice. The level of object representation of 22 moderately obese and 24 normal weight subjects was compared using the Blatt Family Interaction Questionnaire. The mean level of object representation of both parents was lower for the obese subjects than for the normal-weight subjects. This finding supports the structural deficit and external regulation hypotheses of food addiction.     

Measurement and quantification of stereotypy in freely behaving subjects: An information analysis

Stereotypy is typically defined as abnormal, repetitive, and purposeless motor behavior. In this study, stereotypy was more rigorously and generally defined in terms ofH, the typical metric for entropy, and was measured using computer-driven analyses of filtered and digitized video records. This technique was validated using rats treated with d-amphetamine, which has been shown to be an effective stimulant of traditionally defined stereotypy in a wide variety of species. Rats were treated with 0, 1, 2, and 4 mg/kg body weight d-amphetamine sulfate, and their unrestrained behavior was recorded on videotape. Our results confirm previous research that found stereotypy to occur at high doses of amphetamine. However, the present measure of stereotypy brought out additional complexities. Our results indicate that stereotypy occurred at significant levels with low drug doses, and, furthermore, that stereotypy in general was highly dependent upon the level of behavioral complexity considered. Finally, we discuss the advantages of the present metric for studying stereotypy.     

The opponent process theory and affective reactions

Solomon (1980) proposed an opponent process theory to account for motivational and affective dynamics. This theory asserts that the brain avoids extremes of emotional experience by countering the stimulation it receives with an opposite or opponent reaction. Opponent processes are thought to be responsible for the characteristic changes in affective experience that occur over time, and to account for the dynamics of affective response to such stimuli as skydiving and sauna bathing, which have heretofore been difficult to explain. However, the relevance of this theory for affective experiences in general (beyond physical stimuli and addictions) has yet to be demonstrated. The present paper examines opponent process theory predictions in two settings, involving affective responses to situation-scenarios and emotion-provoking slides. In each study, significant habituation to both positive and negative affective stimuli was found, as the opponent process theory would predict. Subjects also showed a reversal of affect when the stimuli were reversed from positive to negative or vice versa. However, contrary to opponent process theory predictions, there was no evidence that withdrawal responses were greater after habituation to the affective stimulus. The only instance of a significant difference in withdrawal responses was actually in a direction opposite to that which the opponent process theory predicts. All other predicted differences were not significant. The opponent process theory, therefore, was not supported in these data and appears to need revision or qualification as to its domains of application.     

Congruency of preferences for family-based gender roles and family satisfaction in two-generation farm families

The present study examines the congruency of family-based gender-role preferences among adult members within intergenerational farm families, and tests the effects of congruency on family satisfaction. From a sample of 71 families (284 adults), results showed that the adult children hold more modern gender-role preferences and that disparities in gender-role preferences impact the satisfaction of the younger generation. The results suggest that to fully understand gender-role preferences in intergenerational relations, gender-roles need to be examined within the context of the entire family.     

Training and credentialing in forensic psychology

The number of training programs in forensic psychology has grown considerably in the past 15 years. Numerous opportunities exist for individuals interested in pursuing careers in the forensic area. Interdisciplinary training in several forms is discussed: J.D. -Ph.D. Programs, specialist Ph.D. Programs, predoctoral internships, and postdoctoral fellowships. Continuing professional education, credentialing, and board certification in forensic psychology are also addressed. Despite the face validity of these various types of training and credentialing, little is known about their relative utilities.     

Adjustment to the stress of simulated captivity: effects of emotion-focused versus problem-focused preparation on hostages differing in locus of control

We instructed 57 subjects about to be exposed to a simulated abduction and 4 days of captivity in either problem- or emotion-focused coping techniques, or we gave them a control orientation presentation. Retrospective self-report data obtained on the Ways of Coping Checklist indicated that subjects tended to use coping processes consistent with the type of prestress preparation they had received. Dramatic fluctuations in State Anxiety scores over the course of captivity indicated that the simulation was perceived to be highly stressful. Subjects given emotion-focused preparation reported the lowest anxiety and emotional distress levels and were rated as exhibiting the lowest levels of behavioral disturbance during captivity. Externals engaged in more emotion-focused coping than internals, but externals given problem-focused preparation responded the most poorly of all subgroups on all response measures. Overall, locus of control differences were of secondary impact (vs. situational variables) in influencing anxiety and adjustment. We discuss the characteristics of the stressor that may have accounted for the major findings and the stressful circumstances under which emotion-focused versus problem-focused coping may be of differential utility.     

Validation of two scales for narcissistic personality disorder

The many theoretical accounts of narcissistic personality disorder (NPD) provide no widely accepted method of identifying persons having this syndrome. Undergraduate scores on the Narcissistic Personality Inventory (NPI) and the Millon Clinical Multiaxial Inventory (MCMI) Narcissistic scale were intercorrelated and were also correlated with the Marlowe-Crowne Social Desirability Scale (MCSDS). NPI and the MCMI subtests correlated significantly with each other, r(146) = .55, p less than .001, but not with the MCSDS. These results further the search for a reliable, valid, and easily administered test for NPD while leaving open the question of the relationship between this syndrome and concern with self-presentation.
